In the title compound, C19H17ClN4 [systematic name: (RS)-4(4-chlorophenyl)-2-phenyl-2-(1H-1,2,4-triazol-1-ylmethyl)butyronitrile], which is the conazole fungicide fenbuconazole, the dihedral angles between the planes of the central benzene and the terminal chlorophenyl and triazole rings are 32.77 (5) and 32.97 (5) , respectively. The C—C—C—C linkage between the tertiary C atom and the benzene ring has an anti orientation [torsion angle = 174.47 (12) ]. In the crystal, C—H N hydrogen bonds and very weak C—Cl inter˚ ] link adjacent molecules, actions [Cl = 3.7892 (9) A forming two-dimensional networks lying parellel to the (101) plane. The planes are linked by weak – interactions ˚ ], resulting in a [centroid–centroid separation = 3.8597 (9) A three-dimensional architecture.

Crystal structure of fenbuconazole Gihaeng Kang, Jineun Kim, Hyunjin Park and Tae Ho Kim S1. Comment Fenbuconazole, [systematic name: (RS)-4-(4-chlorophenyl)-2-phenyl-2-(1H-1,2,4-triazol-1-ylmethyl)butyronitrile], is a conazole fungicide and it has been used for the control of leaf spot, yellow and brown rust, powdery mildew, and net blotch on various agricultural and horticultural crops (Li et al., 2012). However, until now its crystal structure has not been reported. The dihedral angles between the planes of the central benzene and the terminal chlorophenyl and triazole rings are 32.77 (5) and 32.97 (5)°, respectively. All bond lengths and bond angles are normal and comparable to those observed in similar crystal structures (Rizzoli et al., 2009; Yin et al., 2014). In the crystal structure (Fig. 2), C—H··· N hydrogen bonds and weak C3–Cl1···Cg1iv (Cg1 is the centroid of the N2–N3– C18–N4–C19 ring) interaction [3.7892 (9) Å] with a chlorophenyl ring are observed (Table 1), forming two-dimensional networks parelle to (101) plane. In addition, the planes are linked by weak intermolecular π···π interaction between the terminal chlorophenyl ring systems [Cg2···Cg2v, 3.8597 (9) Å], resulting in a three-dimensional architecture. (Cg2 is the centroid of the C1–C6 ring) [for symmetry codes: (iv), -x + 1, -y + 1, -z + 2, (v), -x, -y + 1, -z + 2]. S2. Experimental The title compound was purchased from the Dr Ehrenstorfer GmbH Company. Slow evaporation of a solution in CH3CN gave brown plates suitable for X-ray analysis. S3. Refinement All H-atoms were positioned geometrically and refined using a riding model with d(C—H) = 0.99 Å, Uiso = 1.2Ueq(C) for CH2 group and d(C—H) = 0.95 Å, Uiso = 1.2Ueq(C) for aromatic C—H.

Special details Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Crystal structure of fenbuconazole Gihaeng Kang, Jineun Kim, Hyunjin Park and Tae Ho Kim S1. Comment Fenbuconazole, [systematic name: (RS)-4-(4-chlorophenyl)-2-phenyl-2-(1H-1,2,4-triazol-1-ylmethyl)butyronitrile], is a conazole fungicide and it has been used for the control of leaf spot, yellow and brown rust, powdery mildew, and net blotch on various agricultural and horticultural crops (Li et al., 2012). However, until now its crystal structure has not been reported. The dihedral angles between the planes of the central benzene and the terminal chlorophenyl and triazole rings are 32.77 (5) and 32.97 (5)°, respectively. All bond lengths and bond angles are normal and comparable to those observed in similar crystal structures (Rizzoli et al., 2009; Yin et al., 2014). In the crystal structure (Fig. 2), C—H··· N hydrogen bonds and weak C3–Cl1···Cg1iv (Cg1 is the centroid of the N2–N3– C18–N4–C19 ring) interaction [3.7892 (9) Å] with a chlorophenyl ring are observed (Table 1), forming two-dimensional networks parelle to (101) plane. In addition, the planes are linked by weak intermolecular π···π interaction between the terminal chlorophenyl ring systems [Cg2···Cg2v, 3.8597 (9) Å], resulting in a three-dimensional architecture. (Cg2 is the centroid of the C1–C6 ring) [for symmetry codes: (iv), -x + 1, -y + 1, -z + 2, (v), -x, -y + 1, -z + 2]. S2. Experimental The title compound was purchased from the Dr Ehrenstorfer GmbH Company. Slow evaporation of a solution in CH3CN gave brown plates suitable for X-ray analysis. S3. Refinement All H-atoms were positioned geometrically and refined using a riding model with d(C—H) = 0.99 Å, Uiso = 1.2Ueq(C) for CH2 group and d(C—H) = 0.95 Å, Uiso = 1.2Ueq(C) for aromatic C—H.

Special details Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
